The baby Mermaid wanted Letter Hair! don't ask me why the inner workings of a 7 year olds brain is something I will never understand! So for some strange reason we decided on the letter "T" 
I started with dry hair and parted out the front like this. It will end up being the top of the "T" 
Then I had her face me and put her head down (look at the floor) while I started at the bottom and braided up to the part
Here it is braided up to the top
Then I split the pony that is the stem of the "T" and braided that into the top of the "T" I wish I would have pulled this a little bit tighter! she kind of had a bump on the top that I was not in love with but I guess it is all trial and error when you are braiding a T on someones head!
Here is the "T" from the top
Here is the bottom part of the T and her little pigs hanging down, I tried to talk her into braids all the way down but she knows what she wants!
